Tygabolt Countersunk Sleeve Anchor, Zinc Yellow Passivate: Performance Data

Key things to remember

The essentials from this document in plain words. Check the full document before you rely on a figure.

• ✓Pre-assembled wedge-type sleeve anchor for solid concrete. Tightening the head draws the cone into the sleeve, which expands against the side of the hole.
• ✓Five parts in two anchor sizes: 8mm (M6 thread) 60 and 85mm long, and 10mm (M8 thread) 75, 100 and 120mm long. Property class 8.8, #3 Phillips drive, countersunk head for a flush finish.
• ✓Installation: 8mm anchor in an 8mm hole at least 40mm deep, 8 N-m torque; 10mm anchor in a 10mm hole at least 50mm deep, 25 N-m. Minimum concrete thickness 100mm for both.
• ✓Minimum spacing and edge distance: 50mm for the 8mm anchor, 60mm for the 10mm anchor.
• ✓Working load in tension, 32MPa non-cracked concrete, factor of safety 2.5 for steel and 3.0 for concrete already included: 3.2kN for the 8mm (M6) at 40 to 80mm embedment, 5.8kN for the 10mm (M8) at 60 to 100mm.
• ✓Working load in shear, same conditions: 1.6kN for the 8mm (M6) at 50mm embedment and 50 to 80mm edge distance, 2.9kN for the 10mm (M8) at 60mm embedment and 60 to 100mm edge distance.
• ✓Design resistances (strength reduction 0.60 concrete, 0.80 steel) are also tabled, for engineers.

Who it helps: Builders and fixers choosing a flush-finish anchor for handrails, formwork or service brackets in concrete.
